Thisinvention relates to joint forms or division plates for use in theconstruction of concrete roads or other surfacing structures or matriceswherein joints, parting lines or partial parting lines may be necessaryor desirable.

An object of the invention is to provide a joint form or division platewhich may be used with continuous mat or mesh reinforce ment, withoutthe necessity of such reinforcement being divided or separated at thejoints, and which form or plate will provide the joint or parting line.

Another object is to provide a device which may be attached to the meshreinforcement, and swung or moved to the desired position on thereinforcement after the latter is properly positioned, or the device maybe made an integral part of the reinforcement when it is fabricated andmay beplaced in position with the reinforcement.

Another object is to provide a joint form or division plate having meansfor rigidly sustaining it in position on the reinforcing mesh.

A feature of the invention is the simplicity and economy inconstruction.

With the foregoing and other objectsin view, which will be apparent asthe description proceeds, the invention resides 1n the. construction andarrangement of parts, as hereinafter described and claimed, it beingunderstood that changes can be made within the scope of what is claimed,without departing from the spirit of the invention.

The invention is illlstrated in the accompanying drawing, wherei n-Figure 1 is a PGISP BGtlVG view of one embodiment of the inventionshowing the oint form or division plate in position on the re inforcingmesh.

Referring to Figs. 1 and 2, the joint form 8 is a cross sectionon theline 8--8 of 5,860, :filed June 9, 1925. Application for reissue medSerial No. 342,244.

or division plate 1 is of suitable sheet metal, and is formed with anoffset 1 between the upper and lower edges thereof, although the platemay be of various cross-sections, according to the-cross section ofjoint that is desired.

The lower edge portion of the plate 1 is formed with the hinge sleeves 2which loosely embrace one of the longitudinal rods or wires 5- of thesubstantially fiat reinforcing mesh, such as is commonly embedded inconcrete roads and other surfacing structures. This permits the plate 1to be swung against the mesh in storageand shipment, and the plate maybe swung to erect position when the reinforcing mesh has been placedover the subbase of the road.

The plate 1 may be of any suitable length and has cut therefrom one ormore braces 3, only one brace being shown in Figs. 1 and 2. The brace 3is inclined and has its lower end portion bent into a sleeve 4 .toembrace another longitudinal rod or wire 5 of the mesh, therebyholding'the division plate or 1 construction will be rigid andsubstantial.

The transverse rods or wires of the mesh are indicated at 7, and mayextend through the slits of the plate 1 formed by the braces .3.

The plate 1 may be of any suitable length and may be used longitudinallyor transversely of a road or other matrix, for producing either alongitudinal or a transverse joint. Thus, when the reinforcing mesh isin position with the division plate thereon, the concrete is poured-overthem, and the division plate will divide or separate the concrete alongthe desired line, in order to produce the joint or parting line. Withthe division plate above the reinforcement, as seen in Figs. 1 and 2,the plate only divides the concrete above the reinforcement, but whenthe concrete has hardened it will break below the oint form in thedesired position, and the mesh or reinforcement along the line of theplate.

Fi 3 illustrates the division plate 1 as being at and havin the sleeves2 at its lower edge hingedly em racing one of the rods 5, and braces 3and 9 are struck from opposite sides of the plate and have the sleevesor portions 4 and 10", respectively, at their lower ends embracingotherrods at the opposite sides of the plate. The division plate is thusbraced on opposite sides.

Fi 4 illustrates a division plate 1 extending above and below the meshand formed between its upper and lower. edges with a sleeve portion 2 toembrace the reinforcing rod 5. This division plate will divide theconcrete above and below the mesh.

Fig. 5 illustrates a division plate 1 whose upper and lower edgeportions are in' the same vertical plane, and the intermediate portionof the plate is offset toward opposite sides, as at 2, to engage acrossa pair of rods 5.

Fig. 6 illustrates a division plate 1 having the oblique offset 2forming bends to engage a pair of the rods 5, with the upper and loweredge portions of the plate offset in different vertical planes.

The division plates shown in Figs. 4, 5 and 6 may be welded or otherwiserigidly secured to the reinforcement, and may be applied at the factorywhere the mesh is fabricated or at the locality where the mesh isinstalled.

Figs. 7 and 8 illustrate a joint form or division plate 1 extendingabove and below the reinforcement, and having the offsets 1", with thesleeve 2 at the intermediate portion embracing one of the reinforcingrods 5. Braces 3 are struck from the plate 12 and below the mesh andhave the sleeves 4 to embrace another reinforcing rod. The plate hasnotches or openings through which the rods 7 extend. This division platesubstantially duplicates the division plate of Figs; 1 and 2 above andbelow the reinforcing mesh, using a single structure. However, the .rods7 will require insertion through the plate 1 be fore the rods 5 and 7are' welded or otherwise secured at their points of crossing.
